Leaking at faucet. Removed handle (see picture 2). Tried to remove clear spindle? but it won’t come out (maybe it’s not supposed to). Started to try to turn “nut” as circled in red, as I thought I could replace gasket inside. Did not use force. Is this “nut” supposed to come off? I cannot see an actual gap the nut and the other part of the piping. (See picture 3). Thank you.
